FOREST INSECT INVESTIGATIONS 
F. C. Craighead, Entomologist in Charge 
Dr. F. C. Craighead writes that-one of Mr. A. F. Burgess’s large 
sprayers, with two men to operate it, has been sent to the Yellowstone Na- 
tional Park to be used against the larvae of a sawfly and a tortricid, and 
the spruce budworm, which are defoliating extensive areas of lodgepole pine 
and Douglas fir. Experimental spraying will be completed about the last of 
July and by that time examination will be made by Mr. J. C. Evenden of the 
sprayed timber to note the effect on the larvae, checking up with unsprayed 
surrounding trees. Data will also be obtained as to whether the insects are 
increasing or not. 
R. A. St. George left Washington May 28 to conduct cooperative stud- 
ies relating to the prevention and control of insects affecting crude forest 
products. At Fortsmouth, Va., extensive studies are being conducted to de- 
termine the effectiveness of sulphur dioxide gas, orthodichlorobenzene, and 
creosote in preventing end checking the attack of ambrosia beetles, or pin- 
hole borers, in select grades of cypress which are used for partitions in 
batteries furnished automobiles and airplanes. At High Foint, N. C., con- 
siderable control work was done in treating infested rustic furniture with 
orthodichlorobenzene. About a week was spent at Asheville, N. C.,with A. H. 
MacAndrews, of this Division, who is conducting life-history studies of 
bark-beetles attacking pine trees, and the seasonal cutting of various treess 
Motion pictures were taken by the Department or Agriculture under Mr. 
St. George's supervision of logging operations in the woods and mill at 
Charleston, S. C., showing the approved methods of handling pine to prevent 
worm-hole injury. At Savannah and Clyo, Ga., and Vicksburg, Miss., addi- 
tional motion pictures were taken illustrating methods of handling gum to 
prevent pinhole and wormhole injury. Several pictures were made at Vicks-
